This session will discuss key aspects of mine subsidence engineering and engineering disciplines. The session will focus on the causes of mine subsidence and how mine stability relates to the resulting ground movements. Different mining and geologic conditions determine the mode of failure of the mine. The mode of mine failure in turn affects the resulting subsidence movement. Prediction of subsidence and damage potential are also key aspects of subsidence engineering. Case studies of subsidence damage and mine stabilization will be discussed.
Identify elements of risk associated with construction over mined-out workings;
Review four types of subsidence damage;
Review three primary modes of mine failure and the two types of subsidence;
Discuss best practices of mine subsidence engineering.
Dr. Gennaro G. Marino, P.E., received his PhD in civil engineering in 1985, from the University of Illinois. His thesis topic was related to mine subsidence and structural response to subsidence over room and pillar mines, and he has worked in the area of mine subsidence for over 37 years in various ore fields in the US. His work includes planning, mining, and abandonment stages of room and pillar to high extraction workings, as well as related cause and origin investigations. Marino presently has a PE license in 25 states and is a member of The American Society of Civil Engineers, The Society for Mining, Metallurgy & Exploration and the American Society for Testing and Materials. Marino is also the chairman of the American Bar Association’s Expert Witness Civil Engineering subcommittee. Over the course of his career, Marino has authored over 100 articles and publications on subsidence engineering topics.
